✦ Synopsis

Magnetic resonance spectroscopy (MRS) allows the noninvasive measurement of whole organ metabolism due to the presence of the MR-sensitive nucleus phosphorus 31 in adenosine triphosphate (ATP), its precursors, and break-down products. In small animal liver transplant studies it has been used to analyze the metabolic effects of cold and warm ischemia, hypothermic reperfusion, and the relative efficacy of different organ preservation solutions. In recent large animal studies MRS has been developed to provide continuous dynamic information on ATP metabolism during graft reperfusion and the bioenergetic consequences of altering preservation solutions. These basic experimental data need to be critically evaluated in human liver transplantation. Encouraging preliminary data on many possible clinical applications have already been obtained, such as the assessment of human donor liver viability and posttransplant graft function. At present, the cost and technically demanding nature of MRS may restrict its application to research units.
